7. A sub-menu will appear asking if the vehicle is equipped with A/C or not. Enter the appropriate data.

NOTE: If a vehicle without A/C is entered to have A/C, some fault messages associated with A/C could be generated. If a vehicle with A/C is entered as without A/C, certain fault codes, and displays would be locked out from the SCAN tool user and would not be displayed.
